REINFORCED TRUCK.

Specification of Letters Patent. .Patented lily Application ined :rune i3, 191s. "serial No. 239,710. ff

Be it known that I, GUILFORD S. WVOOD, a citizen of the United States, and a resident of the city of Chicago, inl the county of Cooky and State of Illinois, have invented certain new and useful Improvements in Reinforced Trucks: and I dohereby declare thatthe following is a full, clear, andexact description of the saine, reference being had to the accompanying drawings, and to thenumerals ofA reference marked thereon, which form a vent' bendingof said sills and cross bars inv all directions. ,f Y

`It is an object of this invention to construct a truck wherein the sills and cross ineiiibers are reinforced against bending.

It is 'also an obj ectof the invention to provide a metall truck wherein both the tubular sills and cross members are reinforced .by tubes axially disposed therein.

Another object of the invention is the contudinal andtransverse truck lmembers to afford a strong truck of comparatively light paratively light construction wherein the.

longitudinal and transverse frame members are welded to one another and are reinforced by inner tubes.

Another important object of the invention is the construction of a light weight hand truck wherein the frame sills and cross-- pieces are welded together and reinforced by means of axially disposed members, and wherein the supporting legs or stirrups and the wheel brackets are welded to said frame sills and cross-pieces to obviate theuse of bolts and prevent weakening of the frame sills by drilling the same.

-Other and further important vobjects of this invention will be apparent from the disclosures in the specification and drawings.

The invention (in the preferred form) is PATENT OFFICE.

As shown" on the drawings The hand truck embraces a frame coinprising longitudinal tubes or tubular sills l, ivhichaie'parallel and rigidly held spaced from' one another by means of transverse tubes Wo-rV tubular 'cross-pieces 2, welded at their ends to said tubular sills 1,'to'affordv a `substantially unitary frame construction. The rear ends of the sills l, are swaged or bent downwardly to form handles 3.l The front ends of the sills are open and have lfrictionallyand removably engaged therein a nose consisting of a cross-rail or nosepiece 4, each end of which has integrally formed thereon a passaged shank 5, the end of which is provided with a tapered opening or passage 6, and is longitudinally slotted to form a plurality of curved segment lshaped prongs or friction' wedge members 7. 'A screw bolt 8, projects through each of the passa-ged shanks 5, and threads into a tapered wedge nut 9, which when drawnk .into the tapered opening 6, forces the wedge prongs outwardly into. a tight frictional or iio wedging engagement with the inner' surface of tlie'outerv ends of the framey sills 1, as

clearly shown in Fig. 9, thus removably holding the truck nose in position.V

shown in Figs. 3 and 4,

reinforcing member 10, is axially disposed within each of the sills 1, and the transverse tubes 2, to reinforce the saine andresist upward, downward and sidewise .bending of the truck frame members. Y

W'lieelaxle brackets 11, form a part of the truck, and have integrallyformed or rigidly secured thereon relatively long concave troughs or Seats12, whichv receive the fiontends of the sills 1,sea-tedtlierein. The.

concave troughs 12, are welded tothe sills l, thusobviating the use of bolts anddrilling of said sil-ls. .Integrally formed on the lower portions of the brackets 11, are bearing members 13, forsupp'orting an axle 14,

f upon the transverse tubes. 2,-parallel to the frame sills 1, Land are rigidlyT secured in position by means' of bolts or rivets1-9,V which project through the straps and through the transverse tubes 2, and the reinforcing members 10, thereof. The straps18, serve to support smaller articles upon the truck and prevent the same 'from falling through theV frame, as well as serving asia tie between Vthe transverse tubes to increase the'rigidity of the truck frame.

From the 'construction of the truck asdescribed it will beseen that the truck frame comprises few parts, and inasmuch as the sills, the transverse tubes, the aXle brackets, thev legs and the brace bracket arevall welded i together, the truck frame is substantially a Y the centralV 'portion of each of the transverse tubes 2, is slightly dislied. A squared tube or angular' one piece or aunitary construction? When a load is positioned upon theV truck or a force is exertedV ory appliedl to the frame .sills .and transverse tubes, said sills `.and tubes are held or braced against bending by the squared orfangular reinforcing tubes 10, the edges of which Contact the inner surfaces of said sills and tubes. `This con- Y struction permits the use of fra-ine membersk of great strength'. landj relatively light weight. As shown in Fig. 9, the truck nose is adapted to be readily removed'from the truckframe by vremoval of the bolts 8, thus permitting the use of different types of'y `truck noses.

f l am aware that .numerous details ofconstruction may beV varied through 'a wide rangewithout departing. from the principles of this invention, and I therefore do not purpose limiting the patent granted otherf wise than necessitated by the prior art.' y

I claim as my'invention: f

1..i&'truck frame embracing tubular sills,

ytubular Cross-pieces rigidly connecting said V,sills together,and angular tubes disposed within said sillsand .cross-'pieces to rein-V force the same, said angular tubes having Vthe longitudinalzedges thereof disposedparallel to the axes of said sills'a-ndfrcross- .i

\ pieces.

. V`.2. A' truckframe embracing sills, cylindrical tubes 'rigidly connecting said sills .to-

gether, andv prismatic tubes disposed within 'said sills and. tubes to reinforce the same.` 3. A truck frame including tubular sills,

eylindrieal'cross-tubes jointed at their ends Y to the respective sills and rigidly connecting v"said sills* together, prismatic tubes within said sills and cross tubes to reinforce-the same, eachof the prismati'c tubes within La cross tube'being joinedat its ends to the respective sills. f
